As a reminder of the need to dispose of household appliances separately, the product is marked with a crossed-out wheeled dustbin. Precautions before use Unpack the hob and all associated components, taking care not to lose or mishandle any parts. We recommend that the appliance is installed by a suitably qualified professional and connected to the electricity supply by a qualified electrician, who is a member of the N.I.C.E.I.C. and who will comply with the I.E.T. and local regulations. The appliance must be installed in a purpose-designed kitchen unit and worktop cut out as specified below. This hob (Class 3) has been designed for use only as a domestic cooking appliance. Any other use should be considered incorrect and therefore dangerous. 3
Remove all labels and other packaging materials from the ceramic surface prior to use. Do not modify the appliance in any way as this will invalidate the guarantee and is potentially dangerous. The hob top is not designed for any use other than cooking: any other use (e.g. as a worktop) is potentially dangerous and will invalidate the guarantee. This appliance must be connected to fixed wiring and suitably earthed according to local regulations. Alternative connection, through a 13A plug or through an extension lead must not be used. This appliance must not be installed above a dishwasher, washing machine or tumble dryer as steam may damage the electronic components. The appliance is not intended to be operated by means of an external timer or separate remote control system. Using the Appliance Always switch cooking zones off after use. Take particular care when cooking with oils or fats that may ignite. Cooking pans and utensils and the hob itself become hot during use. Caution, risk of injury to people and pets both during and after use. Ensure no cable from any other appliance can come into contact with the hob top or pans during use. 4
Magnetic objects (such as credit cards or portable electronic devices) must not be placed near the hob during use. Do not place any metal object (other than suitable pans) on the hob. Never cover the hob with any cloth or other cover. This may become hot and create a fire hazard. This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved. Children shall not play with the appliance. Cleaning and user maintenance shall not be made by children without supervision. Metal objects such as knives, forks, lids etc. should not be placed on the hob as they may become hot. Precautions to protect the hob Use of damaged pans or those with raw cast iron bottoms may damage the hob ceramic glass. Abrasive materials such as scouring cleaners and grits may damage the ceramic glass. Avoid dropping objects onto the ceramic glass. Take care not to strike the edges of the hob with saucepans. 5
Ensure that ventilation (as specified under installation instructions) remains free from obstructions. Do not place empty saucepans on the hob. Sugar, synthetic plastics or aluminium foil must not be allowed to come into contact with the heating zones; these may cause permanent damage to the ceramic glass. If these should accidentally fall onto the hob, turn it off immediately and carefully remove them. Take care not to burn yourself. Never place any hot items on the control panel. Warning: Danger of fire: Do not store items on the cooking surface. If a drawer is located below the hob, ensure a horizontal divider is installed leaving a minimum gap of 2cm above it for hob ventilation, and protecting the drawer contents from striking the hob. The divider must be made of material capable of withstanding 65 C above ambient temperature. Never place inflammable items or materials in a drawer or cupboard below the hob. 6 Precautions in the event of an appliance fault If a fault is noticed, switch off the appliance and turn off the electricity supply. Warning: If the ceramic glass is broken or cracked do not use the appliance, turn off the electricity supply to avoid the possibility of electric shock. Contact CDA Customer Support.
There are no user-serviceable parts inside the appliance; all repairs must be performed by a suitably qualified service engineer or similar. See the Troubleshooting section in this manual. Other precautions Ensure that each pan is centred on its cooking zone: The pan base must cover as much of the cooking zone as possible. Do not use aluminium or plastic containers: they could melt onto hot cooking zones. The use of incorrect cookware or any induction adaptor plate designed for non-magnetic cookware is outside the manufacturer s specifications so will invalidate the guarantee. The manufacturer cannot be held responsible for any damage to the hob or consequential damages as a result of such use. Never try to extinguish a fire with water, but switch off the appliance and then cover the flame with a lid, fire blanket or similar. 7
FOR THOSE WITH HEART PACEMAKERS OR ACTIVE IMPLANTS: The function of this hob conforms to current electromagnetic interference standards and thus is in total compliance with legal requirements (2004/108/CE directives). To avoid interference between your hob and a pacemaker, your pacemaker must be designed and programmed in compliance with the regulations that apply to it. As such, CDA guarantee only that our product is compliant. With regard to the compliance of the pacemaker or any potential incompatibility, you should obtain information from the manufacturer or your attending physician. 8
Cooking On Induction The principle of induction cooking is based on magnetic effect. When you put your cookware on an induction zone and switch it on, the electronic boards in the hob produce induced currents in the base of the cookware and instantly raise its temperature. This heat is then transferred to the food inside the cookware. The best cookware to use with induction cooking has thick flat bases, as the heat will be better distributed so cooking more evenly. Most cookware is compatible with induction cooking. There are three ways to check the suitability of your cookware: 1. Use a magnet to see if the base of the pan is magnetic: if the magnet sticks, then the cookware is compatible. 2. Place the pan on one of the cooking zones switched on to power level 4: If the display remains on, then the cookware is compatible. If the display flashes, the cookware cannot be used on an induction hob. 3. Check the instructions or packaging of the pans for the symbols indicating suitability for use with induction. 9

Fitting the Hob Unpacking the hob: Take care not to lose or mishandle any parts. Fitting position of the hob: This appliance must be installed a minimum of 50mm from any back wall and a minimum of 180mm away from any adjacent vertical surfaces, e.g. a tall cupboard end panel. This may be reduced to 100mm if the adjacent surface is resistant to fire (tiles or steel, for example). These dimensions are shown in Fig. 5. Ventilation requirements: This appliance must be installed to allow air to flow freely to the air intake, from the air outlet and in the base and run of units into which it is installed (Fig 3). An air gap of 20mm is recommended immediately below the hob. Failure to allow sufficient ventilation could cause damage to the hob and constitutes incorrect installation, which is not covered by the warranty. Notes: This could be a simple slot cut out of the plinth, or a dedicated ventilation grille. The furniture top rail should not be fitted to the unit. This allows the induction hob to exhaust air into the kitchen space. The recommended ventilation sizes are for guidance only. 23
If fitting a cooker hood above the hob: If a cooker hood is to be installed above the hob, the height of the hood above the hob must be at least 600mm (650mm is recommended) (Fig. 4). If the instructions supplied with the hood dictate that the hood must be installed at a height greater than 600mm, then that height is the minimum required. Wall furniture requirements: The minimum height of any cabinet immediately above the hob is 900mm. The minimum height of any adjacent units (including light pelmets) is 400mm, unless they are manufactured from a material resistant to fire (steel, for example). Notes: Do not position this appliance above a refrigeration unit. The heat generated may cause the refrigeration unit to fail. This appliance is designed to be installed into cabinet units capable of withstanding temperatures of 65 C or greater above ambient temperature. Never place perishable foods, soft items such as tea towels, cleaning products or flammable items in the cupboard or drawer below the appliance. If an oven is to be installed below the hob, the thermal safety system on the hob will not allow the hob to be used at the same time as a pyrolytic programme on the oven. 24
The hob is equipped with an anti-overheating safety device that can be activated if the hob is installed over an oven that is not sufficiently ventilated. We recommend that you increase the ventilation of the hob by creating an opening in the side of the cabinet (8cm x 5cm). WARNING: Do not use inappropriate child protectors or railings with this hob. The use of these devices may lead to accidents. 25
